New submission from Shantanu <hauntsani...@gmail.com>:
The dunder methods on decimal.Decimal accept an extra context argument in the pure Python version which the C version does not (violating PEP 399). This came up in https://github.com/python/typeshed/pull/3633, where Sebastian provided the following summary of the issue: ``` Python 3.8.1 (default, Jan 14 2020, 19:41:43) [GCC 8.3.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> from _decimal import Decimal as CDecimal >>> from _pydecimal import Decimal as PyDecimal >>> PyDecimal(1).__abs__(None) Decimal('1') >>> CDecimal(1).__abs__(None) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: expected 0 arguments, got 1 ``` ---------- components: Library (Lib) messages: 362443 nosy: hauntsaninja priority: normal severity: normal status: open title: decimal differs between pure Python and C implementations _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39722> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
